I found a receiver but I am still interested in a 921, maybe even a additional ordinary receiver for one of the bedrooms. I am in the process of wiring everything now so I am open to whatever you have on the cheap
I have my 6000 and I'm upgrading to 622 but it's gone kookoo with my set: it keeps searching for the signal... do you need it? It has VPSK module, everyhting.
